Big Bad Toy Store has preorders available now.
Right now all we have is concept art, but it looks to me like these could be awesome. With the heroic Captimus Prime and a dreaded Capticon, these could make my day. They are also not too expensive at $26 a piece or $50 for the pair. Some speculation suggests they may not be wearable, but even then it’s an interesting new design to add to the collection.
